' 5 claims.

The invention comprehends an applicator particularlyI suitable for usein hairdressing establishments for the retouching of new growth of hair.

The object of the invention is to provide a device of this nature bywhich liquid dye can be applied to hair near the scalp in a convenientand easily controlled manner Vwithout causing streaks that resultl fromexcess dye running down the hair.

A further object is to furnish anapplicator that will enable theoperator to keep the hands free of stain in the performance of thetinting process.

The applicator is in the form of a thick pencil and has a tip at one endby which the tinting dye is applied. The dye is fed from a reservoirformed in a handle portion, and in one construction of the invention atubular valve is controlled by a lever to permit the liquid t pass tothe tip as required.

In the accompanying drawing, Figure 1 is a longitudinal sectional viewof the invention showing the valve closed, and Figure 2 is a similarview showing the valve open.

Figure 3 is an end View depicting the shape of the tip.

Figure 4 is a perspectiveview of the tip.

Figure 5 is a sectional view of a modied structure, and Figure 6 is anend view thereof.

Like numerals of reference indicate corresponding parts in each gure ofthe drawing.

As shown in Figures 1 to 4 inclusive, the applicator comprises a rigidholder formed in two parts l and 8 having a screw connection 9. The part'I is chambered to contain a supply of the tinting dye. The part 8 is acylindrical piece having a straight bore open at both ends.

Within the cylinder 8 is a tubular valve I0 of rubber having anintermediate constricted p0rtion Ill'. 'This valve tube is formed withan annular flange II at its inner end, which flange is shouldered in thescrew connection 9 so that it is clamped by the member 1 to seal'oi thejuncture. The outer end I2 of the valve tube projects slightly vfrom thecylinder 8 and has a central hole I3.

A tip I4 of suitable .material isafllxed to the protruding end of thevalve tube. The tip may be formed of such material as sponge rubber orfelt, and is preferably of a frustum shape having a rectangular frontface I5. The tip is rearwardly reduced to provide a shank I6 that iscemented or otherwise secured in the hole I3 of the valve tube. Both thecylinder and the valve tube are chamberd ush with the conical surface ofthe tip.

Integral with the cylinder 8 is a seat Il that projects inwardly of thebore so as to substantially conform to the curvature of the constrictedpart of the valve tube. Opposite the seat is a lever I8 pivoted to thecylinder at Il)v and projecting inwardly through a slot. The lever is inthe form of a reverse lcurve, the inner curve of which bears against theconstricted part of the 10 valve tube, While the outer part is a iingerpiece. The lever is spring urged as 'at 20 so as to compress the valvetube to prevent liquid flowing t0V` the tip. A

The applicator is conveniently held in the hand and the tinting dyeapplied by dabbing with the tip. By pressure upon the lever, theconstricted part of the valve tube is enabled to relax, which vprovidesa 'passage for liquid from the reservoir,

as shown in Figure l2..

In the variant form shown in Figures 5 and 6, the holder 2| contains theiluid and has a tapered cap 22 that carries the tip 23. The tip is madeof sponge rubber and the tapered face of the vcap is knurled as at 24 toenable it to be unscrewed at 25 for detachment'purposes. The holder .hasan annular recess 26 Aproviding a finger-grip portion.

It has been found in actual practice that the dabbing action of applyingthe liquid dye causes it to feed through the sponge rubber tip. Thisconstruction is inexpensive to manufacture and n serviceable to use.Furthermore, the feed of the liquid is governed by the diameter of the`shank portion of the tip.

What I claim is:

1. An applicator for tinting hair, composed of a rigid member in theform of a thick pencil, said member consisting of two parts having ascrew connection, one of the parts being cham-I bered to constitute areservoir and the Iother part having a central opening, and a spongerubber tip of a frustum shape converging to a rectangular point, saidtip having a rear shank portion mounted in said hole to which tintingfluid is supplied by the reservoir.

2. In an applicator for tinting hair, a rigid cylinder having a slot at'one side and an integral seat inwardly projecting from the other side, arubber valve tube disposed in said cylinder and having a constrictedpart providing a reduced fluid passage, said seat being engaged with theconstricted part of the valve tube, a lever pivoted on the cylinder andhaving a pressure-applying end extending through the aforesaidslot and tcontacting the constricted part of the valve tube,

a spring normally urging said lever to 'apply clamping pressure on thevalve tube, and a dabbing tip adapted to be moistened by uid deliveredthrough the valve tube.

3. In an applicator or tinting hair, a rigid cylinder having a slot atone side and an integral seat inwardly projecting from the other side,a, rubber valve tube inserted in said cylinder With one end projectingtherefrom and the other end adapted to communicate with a reservoir,said valve tube having an intermediate constricted part providing areduced uid passage, the aforesaid seat being engaged with saidconstricted part of the valve tube, a lever pivoted on the cylinder andhaving a pressure applying end extending through the aforesaid slot andcontacting the constricted part of the valve tube, a spring normallyurging said lever to apply clamping pressure on the valve tube, and adabbing tip fitted infthe projecting end of the valve tube.

4. An applicator in accordance with claim 3, in which the dabbing tipconsists of a substantially frustum shaped piece of absorbent materialhaving a reduced shank portion cemented in a central hole in theprojecting end of the valve tube.

5. An applicator of the class described comprising a rigid holder formedin two parts having a screw connection providing a shoulder, one of theparts constituting a reservoir and the other part forming a cylinderhaving a uniform bore open at both ends, a rubber valve tube extendingthrough the cylinder and having a flange at its inner end fitted againstthe shoulder aforesaid and clamped by the screw connection of the twoparts of the holder, the other end of the valve tube projectingoutwardly of the cylinder part, said valve tube having a constrictedpart intermediate of its length providing a'reduced fluid passage, aseat integral with one side of the cylinder and protruding into the borethereof to engage the constricted part of the valve tube, a spring-urgedlever pivoted at the opposite side of the cylinder and compressing thesaid constricted partagainst said seat, and a dabbing tip of absorbentmaterial iitted in and extending from the projecting end of, the valvetube.
